RE: 1000xf bus problem

[Greg.Chandler]

If you mean dmesg it says this:
e1000: 0000:0d:02.0: e1000_probe: (PCI-X:100MHz:64-bit)  {macaddress}

That's weird... dmesg shows one thing, lspci shows another, and my data
transfers seem to point to the lspci info...

Any idea which I should trust?

what is the dmesh output of e1000 ? it should show you what the card
itself detects (at least the newer drivers since 7.0.x all do). This may
provide some clues as to what the card has detected.
